Can You Really Use A Paint Sprayer As A Pressure Washer?

Have you ever found yourself asking, “Can you use a paint sprayer as a pressure washer?”

Washers are convenient because they produce a fast flow of water, allowing you to clean different surfaces at a much quicker pace. 

But what if you don’t have one? Is it possible to use your paint sprayer? It’s a good question to ask. Be sure to check out this guide to find out if it would work! 

Believe it or not, you can use airless paint sprayers as a pressure washer. Because it's your equipment, you have the option of deciding how you're going to use it. 

This way there will be no damage to the pump and the unit will operate at maximum efficiency.

The airless pump pressurizes the small hole in the tip. However, there are some things you need to know beforehand.

1. Pressure Washers Are Faster

While HVLP paint sprayers and washers are similar because they disperse liquid at a fast rate of speed, there are some differences between the two. 

2. It Can Be Messier With a Paint Sprayer

The HVLP paint sprayers tends to get a bit messier while producing more liquid, but this isn’t much of an issue if you’re trying to power wash a large area and want to get the job done quickly and efficiently.

3. Soap and Water Are Safe For the Sprayer

It’s absolutely safe to put water or soap in HVLP paint sprayers because these are two of the things that you’d need to put in your HVLP paint sprayers when cleaning it out after using it with paint anyway. So, if you decide to add both water and soap and use it for power washing, it’s not a big deal. 

4. You Can Choose Different Power Options

You can choose the type of spray gun that you want to work with for power washer, such as a spray gun with high-volume option with lower pressure. You would just hook up a hose to the “blow” end of the vacuum and a spray gun attachment to the other end.

When using a traditional washer, you can choose from different nozzles that produce water at different degrees to clean various surfaces, such as 15 degree, 20 degree, and even 45-degree angles [1]. 

5. Choose the Right Paint Sprayer

If you plan to use your airless paint sprayers as power washing, look for something with lower air pressure when cleaning fragile items and higher air pressure or too much pressure when working with tougher materials, such as concrete.

Can You Use A Pressure Washer As A Paint Sprayer?

While you can use airless paint sprayers as a washer, it’s not in your best interest to use a washer as airless paint sprayers. Although you can put paint in your low pressure washer and use it to cover surfaces, it’s super messy.  

However, you can use a washer in preparation for using a paint sprayer. Before painting, you want to make sure you remove any dirt and dust from the surface of what you are painting before adding a primer or a coat of paint. 

You can use your washer to clean surfaces such as: 

  • Wood 
  • Metal 
  • Concrete 
  • Decks and Patios 
  • Entryways 
  • Walls  
  • Siding 
  • Gutters 
  • Windows  
  • Fencing 
  • Roofs 
  • Cars 

If you don’t want to deal with a huge mess, it’s best to use airless sprayers when you’re trying to cover different surfaces with a coating of paint, but use your washer to clean the surfaces, first.
